HS 1st year Physics Chapter 1: Experiments

 Title: Experiment on the Heating Effect of Electric Current

Introduction: Host: Welcome, everyone! Today, we will conduct an exciting experiment to demonstrate the Heating Effect of Electric Current.

Materials Required: Host: To perform this experiment, we need:

• A nichrome wire

• A battery

• A switch

• Connecting wires

• A bulb

• A heatproof stand

Setup: Host: We will set up the circuit by connecting the nichrome wire to the battery using the connecting wires. The bulb will be placed in the circuit to indicate the passage of current.

Procedure: Host: Let’s begin!

1. Connect the nichrome wire to the battery using the connecting wires.

2. Include the bulb in the circuit.

3. Now, switch on the battery.

Observation: Host: As the current passes through the nichrome wire, the bulb glows, and the nichrome wire starts to heat up. This demonstrates the Heating Effect of Electric Current.

Explanation: Host: The heating effect of electric current occurs because the electrical energy is converted into heat energy in the conductor. The nichrome wire, being a good conductor of heat, gets heated up, and the bulb glows.

Conclusion: Host: This experiment clearly shows that when an electric current passes through a conductor, it generates heat. This is known as the Heating Effect of Electric Current.

Thank You: Host: Thank you, everyone, for being a part of this experiment. Keep exploring and learning new concepts. Have a great day!
